The Stella SMX Air also incorporates perforated 450D polyfabric on the upper chest for excellent lev- els of airflow during the warm, summer riding months. Extended polyamide stretch material has been incorporated on the rider’s back, shoulders, and sides, with a high-density stretch material on the upper back. The stretch material provides an adaptive fit and a high level of freedom of movement, as well as offers the perfect expansion ability for use with the Tech-Air® 5 Airbag System (sold seperatly).

As the Stella SMX Air ladies jacket has been designed to provide premium ventilation, the jacket also comes with a detachable windbreaker liner to help reduce airflow when it’s not needed, offering optimal climate comfort and versatility. DFS Lite external shoulder sliders paired with Nucleon Flex Plus CE Level 1 shoulder, elbow, and forearm armor together provide impact protection for the Stella SMX Air Jacket, resulting in a CE level A rated jacket overall. Derived from Alpinestars’ MX DNA, the highly ventilated, Stella SMX Air Jacket is the perfect choice for the every-day commuter and weekend rider looking for a versatile and protective street sport jacket for riding in warm climates.
